BURNER-LIFTING MEANS.

eases-e.

Application filed August 30, 1920.

T 0 all whom it may concern:

Be it known that I, JoHN S. BRENNAN, acitizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Burner-Lifting Means; and I do he eby declare that the following is a full, clear, and exact description thereof.

My invention relates to a new and useful improvement in oil burners of the type in which oil is supplied from a constant level source to a burner member including a fuel trough having disposed, therein, a relatively stationary incombustible wick, regulation of the burning action being procured by raising and lowering the burner member bodily to vary its relation to the fuel supply level. lVhen the burner is not in use, its bottom is disposed above the fuel supply level and when it is desired to light the burner, its bottom is moved a considerable distance below the level of the fuel supply to procure ready and complete impregnation of the wick with the fuel, various intermediate dispositions of the burner member effecting different degrees of burning action.

It is the principal purpose of this inven tion to provide means for raising and lowering the burner of simple and compact structure which will be more rigid, and consequently longer lived, than the ordinary burner lifting means.

An additional object of the invention is to cheapen the construction of mechanisms of this nature without decreasing the efficiency thereof, and relates especially to an improved means for attaching the handle and indicator to the operating means proper.

With these general objects in view, the invention consists in the novel features of construction, combination and arrange ment of parts which will be hereinafter more particularly described and claimed, and shown in the accompanying drawing, wherein,

Figure 1 represents a detail elevational view, partly in section, of a burner lifting mechanism constructed in accordance with the invention.

Figure 2 is a detail front elevational view of a portion of the operating handle and its indicator.

Figures 3 and 4c are transverse sectional views taken respectively on the planes of the lines 33 and %4 of Figure 1.

Specification of Letters Patent.

Patented July 11, 1922. Serial No. 407,032.

Referring more particularly to this drawing, it will be seen that the major portions of the structure therein illustrated are disclosed in earlier applications, for instance in the co-pending application, Serial No. 382387, filed May 18th, 1920, and in my Patent No. 1327857, granted J an. 13th, 1920. Such a structure includes a supply pipe branch 1 having a burner supply stem 2 telescopically slidable therein and adapted to support a burner. A horizontal bracket arm 3 is secured to a supply pipe branch 1 by the laterally turned vertical attaching plate 4: and an encircling clip 5, the end of the bracket arm remote from the plate f also being laterally turned as at 6. A brace rod 7 extends parallel to the horizontal portion of the bracket arm and connects the plate at and end 6.

A substantially U-shaped operating bar or strip 8 straddles the bracket arm 3, one of its laterally bent ends providing a crank 9, whereas the other similar end forms a handle attaching portion 10. The crank 9 and the attaching portion 10 rotatably engage the outer surfaces of the laterally turned ends 4 and 6 of the bracket arm, they being journalled on the end portions of the brace rod 7. The crank 9 has a burner head lifting link 11 pivoted thereto, as is customary in structures of this nature.

The end portion of the part 10 of the strip 8 is transversely reduced as indicated at 12 and extended away'from the outer end of said strip (see Figure 1) for disposition in the channel of a handle 13. This handle also carries an indicator 14 which is designed to co-operate with a dial plate 15 supported by the bracket arm 3 and the brace rod 7. Obviously when the handle 13 is rotated the strip 8 will be swung about its pivots to rock the crank 9, and movement of these parts is limited by the engagement between the opposite longitudinal edges of the strip 8 and the bracket arm. This arrangement not only provides a very strong and rigid construction, but also an extremely simple one for the mounting of the handle 13.

I claim:

1. In a burner structure, means for moving a burner head including a bracket arm extended from and secured to the supply pipe, the opposite end portions of the arm being laterally turned, a brace rod connecting the laterally turned pora supply pipe,

ends bent laterally and pivoted on the end portions of said brace rod, one end of the stri formin a crank for a burner headv connecting member, the other end providing a handle attaching portion, and a handle fixed tosaid attaching portion, the opposite edges of said strip being adapted to engage the arm to limit rotation of said handle.

2. In a burner structure, a supply pipe, means for moving a burner head including a bracket arm extended from and secured to the supply pipe, the opposite end portions of the arm being laterally turned, a brace rod connecting the laterally turned portions of the bracket arin, an operating strip having its opposite ends bent laterally and straddling the bracket arm, the ends of said strip being journalled on the brace rod in rotative engagement With the ends of the bracket arm, one end of said strip forming a crank for a burner head connecting member, the other end of the strip being reduced and forming a handle attaching portion, and a channeled handle receiving said reduced attaching portion of the strip in the channel thereof. I

In testimony that I claim the foregoing I have hereunto set my hand at Milwaukee, in the county of Milwaukee and State of \Visconsin. 7
